I've been play spiral knights for over 700 hours and have not found an answer to this question.
-no one seems to care or talk about it
-doesn't seem to affect gameplay
-I'm I missing out on/not getting a large chunk of the game?
-why should I waste minerals on it when I can just craft pet food and sell it for 100 times more money?
